Four members of the Japan Airlines Corp. board want JAL President Toshiyuki Shinmachi and two other top executives out, JAL said Wednesday, amid a revolt highlighting tensions within the nation's top air carrier.

The four board members on Friday demanded the resignation of Shinmachi, JAL Executive Vice President Katsuo Haneda and Senior Managing Director Hidekazu Nishizuka. Shinmachi, however, refused to budge.

JAL management is split over how to turn the company around as it struggles with poor business amid soaring fuel prices and falling passenger numbers, due in part to a spate of safety problems.
